Mold Material/Coating
(OP)
Need mold material or coating to:
1. Survive reaction temperature of 4500F, which produces superheated liquid (Tm=1980F)
2. Act as permanent release agent
3. Withstand 50-1000+ cycles
Thanks.

RE: Mold Material/Coating
What is the substrate and how is it cooled? (what wall temp are you expecting)
Sounds like rocket technology to me.

Corrosion never sleeps, but it can be managed.

If the metal amounts are small and the reation times short I would expect graphite coatings to work.

Also there are coatings that will help extend the graphite molds since the exposure is short, but they are expensive.

Fireclay molds offer the benefit of easy molding slag removal and knockout after the casting.
